Make 20 colors available for line plots #11801

beyarkay · 2022-06-28T17:31:39Z

This change modifies theme.txt so that there are 20 colors available for Arduino's serial plotter.

These colors are taken from matplotlib's tab20 color theme , and can be recreated like:

$ python3
Python 3.9.13 (main, May 24 2022, 21:13:51)
[Clang 13.1.6 (clang-1316.0.21.2)] on darwin

This means that up to 20 individual time series can be plotted before the colors recycle, and these 20 colors are also reasonably different from each other so that you can tell them apart.

First time contributor here, please let me know if there's any changes I should make! love the tool and am happy to help out. This was a personal gripe of mine, as I'm currently working on a project that needs 15 sensors (accelerometer data in 3 dimensions for 5 fingers).
